As　a　crucial　material　for　road　repairs,　the　emulsification　performance　of　emulsified　asphalt　directly　affects　its　storage　stability　and　construction　efficiency.　This　study　systematically　analyzes　the　effects　of　emulsifier　blending,　emulsification　temperature,　soap　solution　pH,　and　stabilizer　dosage　on　emulsification　performance.　The　results　demonstrate　that　the　emulsifier　blend　of　Y13　and　Y2　at　a　ratio　of　8:2　achieved　optimal　emulsification　and　stability.　The　ideal　emulsification　temperature　was　found　to　be　65　±　5　°C,　with　a　soap　solution　pH　range　of　2　∼3,　and　the　stabilizer　dosage　should　be　controlled　within　3.0‰.　This　study　provides　theoretical　guidance　for　the　design　and　application　of　asphalt　emulsifiers.　　©　Published　under　licence　by　IOP　Publishing　Ltd.
